NV. 24, 1936. K ARNQLD I 2,062,046 MECHANICAL TY v' Filed May 8, 19315 NVENTOR -Jzzw' w Patented Nov. 24, 1936 UNITED STATES MECHANICAL 'roY Karl Arnold, Nuremberg, Germany Application May s, 1935,fsoiia 1No. 20,391 In'Giermany March 2,3, 1935 6 Claims. (Cl. 46-217) This invention relates to a mechanical toy in which any desired facsimiles of toys are moved in a straight line' on a track, then turned through 180, that is about their vertical axis, on reaching the two extreme points of the travel, and run in the opposite direction until they are again turned. At the same time other toys hitched on to the facsimile toyare automatically hooked unto a carrying arm and uncoupled land also drawn along, that is, are moved backward and forward.

This is attained by fixing on an endless chain, rubber`endless `track, endless band or the like driven directly or indirectly by a motor, and supported on a pair of carrying discs, an arm bent twice at right angles, the horizontal part of this arm being of a length extending to midway between the two sides of the endless chain.I This arm is at the same time constructed for carrying the facsimile toy.

An embodiment of the invention is illustrated by way of example in the accompanying drawingA in which:-

u Fig. 2 shows a part of the toyon a larger scale,

the main parts being in longitudinal section.

. 0n a base platel a driving motor-2 is mounted which carries on its underside a star wheel 3 on an extension of its driving axle. The plate I also has two brackets 4 serving as bearings for one end of shafts 5 journalled at their other end in a bar 6 extending longitudinally in the toy. One shaft 5 carries on its upper enda carrying disc 'l and on its lower end a star wheel 8, whereas the other shaft only carries a carrying disc 1'. An endless n chain 9, rubber endless track, endless band or the like 9 passesaround the periphery of these carrying discs 1 and 1' and the two star wheels 3 and 5 are connected by a chain I0 and driven by the motor 2, thus circulating the endless chain 9 and rotating the carrying Vdiscs 1 and 1'. The driving motor 2 can rotate these discs directly or througl the intermediary of a bevel wheel gearing instead of by means of the chain drive. A plate II is attached to the chain 9 by pins or the like. This plate has an arm I2 bent at right angles to form a horizontal part I2 extending to midway between the two sides of the chain and then bent up at right angles and enlarged to a vertical plate I6. The horizontal part I2 of this arm is so long that its upwardly bentportion travels in thev middle of the bar 6. Thus' twice in a complete circulation of the chain 9 around the carrying discs 1 and 'l' the arml I2-I6 will be turned about its own axis through an angleof ".v If,jas shown in theI drawing, a facsimile locomotive is iixed on the 5 part I6 of the arm, this locomotive also turns through without travelling beyond the axis of the shaft 5. Thus a natural turning movement of thelocomotive is simulated. The whole driving mechanism is covered by a plate I4 forming l0 a track for the locomotive and having a slot I3 and xed on or pressed in one piece with the base plate. On the two ends of the plate facsimiles of 4 vhouses I5 are mounted and provided with apertures. The part I6 of the arm forms a part of l5 the locomotive, for example the funnel, dome,- Whstle and driver. The simulated locomotive Il provided with a slot I8 is slipped over this part I6.

The toy operates in the followingmanneri-e The toy represents a true imitation of the rst -20 railway. When the driving motor 2 has been wound, the chains I0 and 9 are caused to circulate.' The arm I2-I6 iixed on the chain 9 participates in this movement with the simulated locomotive removably mounted, on part I6 of the 25 arm. The locomotive is turned through an angle of 180 when the chain 9 moves the arm in a circle because the part I6'oi which always remains in the 'central longitudinal plane of the bar 6. During this movement a toy'vehicle I9 can be 30 hitched to or unhitched from the locomotive. For this purpose the two vehicles have hookshaped coupling arms 20 and 2| bent upward and downward respectively. As can .be seen from the drawing, the locomotive I1 draws a waggon I9 35 until the turning movement takes place. During this turning movement the arm 20 unhooks from the arm 2|. The waggon remains'at a standstill whilst .the locomotive is turned through an angle of 180. At the termination of this movement the 40 locomotive shunts the waggon into its original position. When the locomotive reaches its other turning point, the waggon is left standing still and the locomotive is turned through an angle of 180. During this movement the coupling arms 2Il and 2| are again hooked the one over the other so' that the coupling is eiected whereupon the locomotive moves forward with the waggon. To ensure a straight guiding of the waggon I9 it has a plate 50 22 projecting downwards from its underside and engaging in the slot I3 in the cover plate or truck Il.- 'I'he above described operations are repeated in succession until the motor has run down.

'I 'he invention may be employed for all manner 55 of toys in which a turning through an angle of 180 is required.

I claim:-

1. A mechanical toy comprising in combination a motor driven endless chain, a plate i'lxed on said endless chain and bent atl right angles to form a horizontal-part extending to midway between the two sides of said endless chain and then again bent up at right angles to form a vertical plate, a toy imitating a'locomotive placed on -the said vertical plate, a hook shaped arm at the rear of y said toy open in upward direction, a second vehicle and a downwardly directed hook at the front end of said second toy adapted to automatically hitch over said hook shaped arm of the front toy and to unhitch from the same every time said front toy is running over a reversing point of said endless chain.

2. A mechanical toy as specified in claim 1, in which the rst toy is an imitation of a locomotive of the rst railway and has a. slot in its bottom plate to be slipped over the vertical plate.

3. A toy as specified in claim 1, comprising in combination with the endless chain and the toy vehicles to be hitched on and unhitched, a track plate covering saidchain and having a slot midway its side edges, and a downwardly projecting plate on the bottom plate of each of said toy vehicles engaging with the slot of said track plate;

4. A toy as specified in claim 1, in which the vertical plate carries a facsimile of a toy and itself forms part of said facsimile having a slot adapted to receive the upper portion of said lever.

5. A toy as specied in claim` l, comprising in combination a facsimile of a toy mounted on said vertical plate, a casing enclosing the circulating endless member, a cover plate of said casing, a longitudinal slot for the passage ofthe upwardly bent portion of said lever and forming a support for said facsimile, a toy separate from said facsimile movable on said cover plate, a coupling lever on said facsimile, and a counter coupling lever on said separate toy, said levers adapted to alternately engage and disengage during the turning movements of said lever at the two extremities of its movement.

6. A toy as'speciiied in claim l, comprising in combination a facsimile of a toy mounted on said vertical plate, a casing enclosing the circulating endless member, a cover plate of said casing, a longitudinal slot for the passage of the upwardly bent portion of vsaid lever and forming a supportn
